摘要

The present study demonstrates the use of triazole moiety in designing molecules endowed with the ability for self-assembly and molecular recognition. The receptors 7a and 9a having open structures bind to fluoride ion with good affinity. Various cyclophanes with 19-, 20-, 21-, 38-, and 40-membered rings containing triazole units were designed and synthesized. X-ray crystal structure of macrocycle 16 showed a tubular like architecture. Triazolophane 22 possesses bifurcated CH center dot center dot center dot N intramolecular hydrogen bonds and it further organizes in the solid state using CH center dot center dot center dot N interactions. Triazole based compounds are potential store house for exploiting CH center dot center dot center dot O and CH center dot center dot center dot N hydrogen bonding interactions for molecular self-assembly.

Discovery of intracellular self-assembly protein degraders driven by tumor-specific activatable bioorthogonal reaction

Ru Si, Ping Hai, Yongbiao Zheng, Jin Wang, Qingqing Zhang, Yanchen Li, Xiaoyan Pan, Jie Zhang

Summary: Proteolysis Targeting Chimera (PROTAC) is a bifunctional molecule that degrades binding proteins through the ubiquitin-proteasome pathway. Despite its potential in overcoming drug resistance and targeting undruggable targets, PROTAC faces challenges such as poor membrane permeability and bioavailability due to its large molecular weight. In this study, we used intracellular self-assembly to construct tumor-specific PROTACs using small molecular precursors. These precursors, incorporated with azide and alkyne as bioorthogonal groups, reacted with each other under the catalysis of copper ions in tumor tissues, resulting in novel PROTACs. These intracellular self-assembled PROTACs effectively induced degradation of VEGFR-2 and EphB4 in U87 cells, as well as promoting apoptosis and blocking cells in S phase. The high selectivity of these tumor-specific intracellular self-assembled PROTACs was attributed to the high concentration of copper ions in tumor tissue. Additionally, this strategy reduced the molecular weight of PROTACs and improved membrane permeability. These findings greatly expand the application of bioorthogonal reactions in the discovery of novel PROTACs.
